Drogendelinquenz JugendstrafrechtsreformIn this chapter we study some fundamental questions of combinatorial geometry. The objects of this study are finite sets of points and finite arrangements, i.e., finite sets of lines or hyperplanes. As an introduction let us look at three classical contributions to this area.

Interviewpartner und Informanten,It can be very useful to have combinatorial representations of geometric objects. The combinatorial structure of such an encoding may be easier to analyze and manipulate than the original object.

Drogenkonsumkontrollen am Arbeitsplatz,A . is a graph . = (.) and an embedding p: V → IR.. The straight edges of the framework are thought of as rigid bars connecting vertices (joints) where incident bars are connected flexibly. An important problem for civil engineers, is the question: “is a given framework rigid?”

,Geometric Graphs: Turán Problems, through basic notions from graph theory and report on facts about planar graphs. Beginning with Section 1.4 we discuss problems from the extremal theory for geometric graphs. That is, we deal with questions of Turán type: How many edges can a geometric graph avoiding a specified configuration of ed

Schnyder Woods or How to Draw a Planar Graph?,stion and more a matter of taste. In the graph drawing literature many answers are offered. In this chapter we present some results about drawings and other representations of (3-connected) planar graphs. The results are based on the structure of Schnyder woods.
